A method of altering the force balance characteristic or moment configuration of an earth-boring rotary-type drill bit by altering the net hydraulic direction vector of drilling fluid exiting from the drill bit and, therefore, the accompanying net hydraulic force exerted on the drill bit. The method includes replacing at least one nozzle of the drill bit with a differently sized nozzle to alter the amount of hydraulic force that is exerted on a particular portion of the drill bit. Alternatively, the orientation of at least one nozzle of the drill bit may be changed to alter the direction in which drilling fluid flows from a particular portion of the drill bit and, thus, alter the direction of the hydraulic force on the drill bit. The method may be employed to counteract a net force imbalance of a drill bit, to alter a direction of net force imbalance, or to vary the magnitude of net force imbalance.
